Need to go! - Our guide was absolutely amazing! It took about an hour to get to the end and then you can walk back yourself, For the price I think it’s absolutely worth it! You learn a lot and it’s just a lovely experience overall!

Wonderful experience - Awesome! Very cool lava tube with beautiful colors, textures, and skylights! Stunning when the water drops freeze in a pile and the lights shine through them. They look like a bunch of candles. We highly recommend this activity!

Amazing Experience - Very well organised. You are provided with everything you need (helmet, crampons & walking stick). The lady who was our guide was amazing. She made it very interesting and you could tell how much she loves her job. Full of enthusiasm and made us feel safe and able to ask questions. Would defiantly recommend this trip to anyone visiting Iceland.

Amazing experience but expensive - Our tour guide Juan was amazing and the lava cave was a great experience. Juan was very knowledgeable, funny, and interactive with the large group. It was a little pricey being $100 for an hour but everything else was great.
